When Erica Hahn left the orthopedic surgeon outside of the hospital with one last parting shot, she honestly didn't think it would be more than a blimp in the radar for the woman.

Callie Torres was not in it for the long haul.

…Right?

Wrong.

The blonde was the reason for the other woman's current location: OR 3.

Erica Hahn was the reason Christina Yang thanked some higher power that she was home earlier that night, and definitely for the fact she works as a doctor; the usually unaffected woman had the shock of her life that night: Calliope Torres on the brink of unconsciousness, a note held loosely in her left hand, and a scalpel in the other, bleeding out.

Yang sat in the waiting room, staring at the note her friend had meant to leave the world with, her blood practically boiling. It read, "Why didn't you believe me, Erica?"

Her blood was officially boiling, and the chief was about to get the brunt of it.

"Yang—"

"I demand you to bring Dr. Hahn to this hospital right now."

"You're demanding me?"

"Get Erica Hahn here right now, before I go out and find her myself, and trust me when I say you won't like the outcome."

After what felt like a lifetime, the cardiothoracic surgeon walked towards her student. The younger woman shook her head, trying to remove the images of her friend's bloodied forearms.

"Chief said you needed me, Yang?"

She let out a bitter laugh, "Need you? I don't need you."

"Excuse me? I could have you kicked out this program for that."

"So, what's the count now? In this hospital, as far as I know, it's only one doctor at this point."

"What are you talking about?"

She didn't respond verbally, grabbing the older woman's arm roughly, dragging her to the gallery, wanting her to see what she had.

The many interns any doctors who filled the room looked up, gasping as they saw whom Christina was man handling.

She practically threw her against the glass, snarling a "See what you did? Why didn't you believe her?"

Miranda Bailey looked up from her work to see Christina push the blonde woman against the glass. Her only response was a brief glare directed to the woman, having heard Callie's pleas for the doctors to stop their work, herself included.

"I didn't do anything, Yang!"

"Exactly. You did nothing." She let out a cynical laugh, "That isn't even the worst of it. What you see down there? That's practically as good as new compared to how she was when I found her."

"None of that is my fault, Dr. Yang, and I suggest you let go of me before you're banned from every decent medical program in the country."

She didn't let go, "You can't buy your way out of it this time."

The blonde yelled, "How many times do I have to say this wasn't my fault?"

"However many times you want, but it still won't be true."

"You're not Callie, so you have no clue what caused this!"

"No, I'm not Callie, and I may not know exactly what caused this, but I do have a general idea."

"Oh, really? And how do you know this?"

"Her note; 'Why didn't you believe me, Erica?'" The blonde was shell-shocked, "Six words have never done so much damage, have they?"

She thought back to her words earlier that night, 'I don't know you. At all.'

Callie used her own six words; six words with the intention of being her parting shot to the world.
